The divisional application that the application is the applying date is on 03 05th, 2008, application number is 200880129137.X, denomination of invention is the Chinese patent application of " for providing the method and apparatus strengthening signaling ".
Technical field
Concept described herein relates generally to the method and apparatus in network.More particularly, described herein concept relates to the method and apparatus not affecting legacy device for utilizing resource to provide enhancing signaling in communication standard.
Background technology
The down link of Long Term Evolution (LTE) or Evolved Universal Terrestrial radio access network (E-UTRAN) transmits based on OFDM (OFDM).Such as, as shown in fig. 1, LTE down link can be modeled as OFDM temporal frequency grid 100, and wherein, each resource element 105 may correspond to an OFDM subcarrier in an OFDM symbol interim.Downlink subcarriers interval can equal 15kHz.
In a frequency domain, downlink subcarriers can be grouped into Resource Block, and wherein, each Resource Block comprises 12 continuous print subcarriers.LTE physical layer standard allows downlink carrier to comprise any amount of Resource Block of 6 and more multiple resource block.
Fig. 2 illustrates the demonstration spatial structure 200 transmitted for LTE down link or up link.As shown in the figure, LTE transmits and can comprise radio frame 205.Each radio frame 205 can be equivalent to 10 milliseconds (ms), and can comprise a series of subframe 210.Each subframe 210 can have the duration of 1ms.Subframe 210 can comprise two time slots 215.Each time slot 215 can have the duration of 0.5ms.
Fig. 3 illustrates the demonstration spatial structure 300 for time slot 215.Time slot 215 can comprise multiple OFDM symbol.
LTE standard defines two Cyclic Prefix (CP) length, a common CP 305 and an expansion CP 320.Common CP 305 can comprise seven OFDM symbol, and expands CP 320 and can comprise six OFDM symbol.In addition, common CP 305 can comprise CP 310 and CP 315, and wherein, the comparable CP of CP 310 315 is longer so that the whole 0.5ms of filler timeslot 215.Expansion CP 320 can comprise CP 325.Expansion CP 320 sends employing by multicast/broadcast Single Frequency Network (MBSFN).
In the time domain, Resource Block can be made up of the subcarrier of 12 during 0.5ms time slot.Therefore each Resource Block is made up of 12x7=84 resource element when using general cyclic prefix, and when using extended cyclic prefix, is made up of 12x6=72 resource element.
According to LTE standard, downlink reference signal can by being that oneself that insert OFDM temporal frequency grid knows that the reference symbol of symbol forms.Among other things, reference signal can be detected to make it possible to be concerned with for Downlink channel estimation by subscriber equipment (UE).In addition, in LTE standard, downlink antenna port corresponds to the visible antenna of UE, and antenna has unique set of reference symbols (that is, an antenna mapping is to an antenna port).But in other realizes, multiple antenna can be mapped to same antenna port, transmits identical set of reference symbols, and may be undistinguishable to UE.
At present, the reference symbol of three types is had can to transmit on LTE down link: the specific reference signal in community, MBSFN reference signal and the specific reference signal of UE (being sometimes referred to as DRS (Dedicated Reference Signal)).The specific reference signal in community may correspond to and transmits antenna port (maximum four) in down link.MBSFN reference signal can be relevant with MBSFN frame.The specific reference signal of UE can transmit on the uplink, and can be used for channel estimating by certain UE or UE group.
Fig. 4 illustrates demonstration OFDM temporal frequency grid 400.OFDM temporal frequency grid 400 relates to the single transmission antenna be associated with antenna port 405.As shown in the figure, the specific unicast reference in community signal can insert in specific resource element.That is, reference symbol 410 can be inserted in last resource element first of time slot and the 3rd.A Resource Block comprises four reference symbols.
When line link multiple antennas transmission under use (that is, transmitting diversity and spatial reuse), UE can identify and estimate the channel corresponding to each transmission antenna.Therefore, there is the downlink reference signal transmitted from each antenna port.
Fig. 5 A and 5B illustrates the demonstration OFDM temporal frequency grid 500 transmitting antenna port 505 and 520 with two and be associated.As shown in the figure, the reference symbol 510 of antenna port 505 has the frequency shift (FS) of three subcarriers relative to the reference symbol 525 of antenna port 520.The OFDM temporal frequency grid 500 of antenna port 505 comprises untapped resource element 515, and the OFDM temporal frequency grid 500 of antenna port 520 comprises untapped resource element 530.In this regard, the interference of reference symbol between different antennae port is not had.Fig. 6 A-6D illustrates and to transmit demonstration OFDM temporal frequency grid 6000 that antenna port 605,620,635 and 650 is associated with four as shown in the figure, and reference symbol 610,625,640 and 655 can transmit from antenna port 605,620,635,650 respectively.In addition, what OFDM temporal frequency grid 600 comprised respective antenna port 605,620,635,650 respectively does not use resource element 615,630,645 and 660.The reference symbol density of antenna port 635 and 650 can be less than the reference symbol density of antenna port 605 and 620.Down link ground floor suitably receives for transmitting UE with the second layer (L1/L2) control signal, downlink scheduling required by demodulation code downlink sharied signal channel (DL-SCH) is assigned, the relevant resource that transmits for up link (UL)-SCH of notice UE and the uplink scheduling license of transformat and mixed automatic repeat request (ARQ) confirmation of response UL-SCH transmission.
Fig. 7 illustrates the demonstration OFDM temporal frequency grid 700 of the subframe 705 with time slot 710 and 715.(nearly three) OFDM symbol of foremost in the subframe that down link L1/L2 control channel is mapped to such as subframe 705.Therefore, subframe 705 can comprise L1/L2 controlled area 720 and data field 725.The large I of controlled area 720 equals the OFDM symbol (such as, two or three OFDM symbol) of integer amount, and can often subframe 705 is different.In this regard, control signal expense adjustable is to meet service conditions and to be maximized by spectrum efficiency.In addition, by locating L1/L2 control signal in the beginning of subframe 705, UE can by L1/L2 control signal (such as, downlink scheduling is assigned) decoding before the end of subframe 705.Therefore, such as, the decoding of DL-SCH directly can start and need not wait for the decoding of L1/L2 control information behind the end of subframe 705, and this can will drop to minimum with the decode delay that is associated and/or always down link propagation delay of DL-SCH.Additional or alternative, by transmitting L1/L2 control information in the beginning of subframe 705, the UE do not dispatched can close its acceptor circuit to reduce power consumption for the part of subframe 705.
Down link L1/L2 control signal can be mapped to following physical channel: physical control format indicator channel (PCFICH), physical downlink control channel (PDCCH) and Physical Hybrid ARQ Indicator channel (PHICH).
PCFICH is for notifying that UE is about the quantity (such as, one, two or three) for the OFDM symbol of L1/L2 control signal in present sub-frame, or considerably, notice UE data field in subframe starts from where.If PCFICH decoding error, then UE will not know to find control channel wherein, not know that data field starts from where yet, and any uplink scheduling license and expection of losing transmission are used for any DL-SCH data transmission of UE.
Fig. 8 illustrates demonstration PCFICH processing scheme 800.As shown in the figure, use the single work frame 805 of such as speed 1/16, will corresponding to one, the dibit information coding of the controlled area size of two or three OFDM symbol (the 4th bit combination is retained in order to using in the future) is in the sequence of 32 bit long.12 resource elements that the bit of encoding is modulated (815) by scrambling (810), Quadrature Phase Shift Keying (QPSK) and is mapped in controlled area 820.For compatible from the different transmission diversity schemes of specifying in the group of four symbols, 16 resource elements are grouped into four groups, each group of four elements.Four groups at frequency halving every to obtain diversity.In addition, for avoiding minizone PCFICH to conflict, in frequency domain, the position of four groups can be depending on physical-layer cell identity.The delivering power of PCFICH can be under the control of enhancing Node B (eNodeB).If be necessary for the covering in specific cell, then by " using " power from such as PDCCH, the power of PCFICH can be set to higher than other channel.
PDCCH is used for carrying downlink scheduling and assigns (such as, physical down link sharing channel (PDSCH) resource indicates, transformat, hybrid ARQ information, transmission block size, the control information that multiple-input and multiple-output (MIMO) is relevant and/or physical uplink control channel (PUCCH) power control command), uplink scheduling license (such as, physical uplink link shared channels (PUSCH) resource indicates, transformat, hybrid ARQ information and/or PUSCH power control command) and/or UE group power control command (such as, as for be equipped with scheduling judge power control command supplement).
Owing to can dispatch multiple UE on the downlink and uplink simultaneously, therefore, multiple scheduling message can be transmitted in each subframe.Such as, this type of message each transmits on independent PDCCH, therefore have multiple PDCCH in each community, and each UE can monitor multiple PDCCH.
Different scheduling messages can have different pay(useful) load sizes.Such as, carry out multiplexing may the requirement of support space by the discontinuous distribution of Resource Block in frequency domain and permit larger scheduling message than the up link of support continuous dispensing.Link circuit self-adapting (that is, making the encoding rate of the error correcting code of PDCCH mate instantaneous radio conditions) also can be supported.Therefore, may be useful in the different-format of PDCCH, wherein, each form can according to pay(useful) load size and encoding rate undefined.
Fig. 9 illustrates demonstration PDCCH processing scheme 900.As shown in the figure, cyclic redundancy check (CRC) (CRC) 905 is attachable to each PDCCH pay(useful) load (such as, PDCCH-1, PDCCH-2 etc.).Medium education (MAC) identifier (such as, radio network temporary identifier (RNTI)) can be included in CRC calculating.
After attached CRC, chnnel coding 910 can be performed respectively (such as, sting tail (tail-biting) convolution code), rate-matched 915, scrambling 920 and QPSK modulation 9250 according to PDCCH message size (namely, support three size: size A, B and C) and channel encoding rate (comprising rate-matched), the size of the PDCCH of coding may correspond in one, two, four or eight control channel elements (CCE).Each CCE may correspond in 36 resource elements (for such as 5 megahertzes (MHz) bandwidth of cell).
The PDCCH of modulation can carry out multiplexing 930.In one implementation, can be all CCE etc. corresponding to PDCCH-2 after all CCE corresponding to PDCCH-1.Multiplexing CCE such as can be mapped to resource element to support different transmission diversity schemes in the group of four QPSK symbols.Can scrambling 935, intertexture 940 be carried out to multiplexing CCE and/or offset by cell specific offset 945 subsequently.The specific shift unit 945 in community can map between different districts in randomization.
After reception PDCCH pay(useful) load, UE can use its oneself identifier (such as, RNTI) to check CRC.If CRC confirmation, then PDCCH pay(useful) load can be declared as correct reception and expect for UE.Like this, the identity of the UE of expection reception PDCCH pay(useful) load implicit expression can be coded in not explicit transmission in CRC.
Not can be used for the transmission of PDCCH for the resource element of reference signal in PCFICH, PHICH or controlled area.Additional or alternative, in one implementation, each CCE can be mapped to cross over all OFDM symbol in controlled area, thus between OFDM symbol, provide uniform power to distribute and allow power to control.
Be similar to PCFICH, the delivering power of each PDCCH can be under the control of eNodeB.Except adjustment encoding rate, power adjustment can be used as supplementary link adaptation mechanism.Although power adjustment itself can be a kind of link adaptation mechanism, only rely on power adjustment and can cause difference power larger between PDCCH, realize angle from radio frequency (RF), this may have impact.In this regard, different encoding rates and power adjustment can be used as supplementary link adaptation mechanism.
As described with reference to Fig 9, each PDCCH can support multiple form, and the form adopted can be priori the unknown to UE.Therefore, UE may need the form of blind Detecting PDCCH.Monitor the requirement of multiple PDCCH (each with unknown format) for UE can seem be quite high quantity decoding attempt.But, if adopt fixing CCE size, and only allow specific CCE aggregation size (such as, two, four or eight CCE), then can reduce the number of times that blind decoding is attempted.Figure 10 illustrates the blind PDCCH decoding scheme 1000 of the demonstration occurred in UE.
PHICH can be used for the transmission responding the hybrid ARQ confirmation that UL-SCH transmits.Expection is had in subframe to each UE of confirmation, a PHICH may be had to exist.
Figure 11 illustrates demonstration PHICH processing scheme 1100.As shown in the figure, each PHICH can carry a bit, this bit can (1105), modulation (1110), use spreading factor (such as, four) be expanded (1115), and add (1120) to other PHICH in triplicate.That is, multiple PHICH can form PHICH group, and the PHICH in PHICH group that such as different orthogonal spreading sequence can be used to carry out code is multiplexing, and PHICH group can share identical set of resource elements.When adopting code division multiplexing (CDM), the difference power between subcarrier can be large unlike during employing frequency division multiplexing (FDM).If expect the more PHICH capacity in single PHICH group (such as, corresponding to 12 resource elements), then configurable other PHICH group.In each PHICH group, can CDM be used, and can FDM be used between PHICH group.After other PHICH of interpolation, can by PHICH scrambling (1125) and three groups be mapped in controlled area 1130, each group has three resource elements.
The power setting of PHICH and PHICH error rate therefore can not specified, but can be considered it is problem of implementation.But, 3GPP supposition 10
-2aCK to NAK error rate and 10
-3to 10
-4nAK to ACK error rate in scope can be suitable LTE design.Reason is that NAK to ACK error rate can imply the loss at MAC layer transmission block.This is lost to be retransferred by radio link control (RLC) with associated delay and recovers.Because PHICH target error rates is lower than PHICH error rate, therefore, PHICH maps and can be designed to not depend on PCFICH value.Therefore, semi-static configuration can be used for for PHICH reservation of resource.
PHICH can only transmit in the first OFDM symbol.But in other cases, this type of scheme may unnecessarily limit PHICH and cover.In this regard, other scheme can comprise the PHICH duration of configuration as three OFDM symbol.In the case, in all subframes, controlled area can be that three OFDM symbol are long.But in other cases, the PHICH duration can be longer or shorter.Such as, when using hybrid unicast/MBSFN sub-frame, the PHICH duration can be two OFDM symbol.
PHICH configuration can be the part (Master Information Block (MIB) such as, on broadcast channel (BCH)) of system information.A bit can indicate the duration to be such as one or three OFDM symbol, and two bits can be designated as the stock number that PHICH reserves.UE can expect the scheduling grant of confirmation from it, explicit instruction can be there is no.On the contrary, the PHICH numbering for transmitting confirmation can be derived from a CCE quantity of the PDCCH carrying license.
In LTE design, multimedia broadcast/multicast service (MBMS) can be provided.Such as, single cell point can be adopted to arrive multileaving and/or multiple cell Single Frequency Network operation (also referred to as MBSFN).In MBSFN, can use same asset (such as from all communities, identical Resource Block set) and/or the cell set of identical traffic form (such as, identical encoding rate and/or modulation scheme) transmit identical broadcast/multi broadcast information simultaneously.When this type of MBSFN transmits, the signal with the time difference in the span of CP during the arrival UE transmitted from different districts can be considered as being single gathering signal by UE.In this regard, the use that MBSFN transmits can increase the signal power of reception and/or eliminate quite most presence of intercell interference.Therefore, the possible throughput of MBMS can be improved greatly.
In LTE framework, MBSFN transmits and can carry out in the specific sub-frame being called MBSFN sub-frame.According to the amount of the MBMS capacity such as needed, the different piece of the whole set of downlink subframe can be designated as MBSFN sub-frame.But generally, it is non-MBSFN sub-frame (but not necessarily effective under the so-called special MBSFN carrier case of use) that the subframe of frame is caught with subframe code.
Figure 12 illustrates demonstration MBSFN sub-frame framework 1200.As shown in the figure, MBSFN sub-frame 1205 can comprise two parts: uni-cast portion 1210 and MBSFN part 1215.
Uni-cast portion 1210 can comprise one or two OFDM symbol.In uni-cast portion 1210, L1/L2 control section 1220 signaling (that is, the signaling of PCFICH, PHICH and/or PDCCH) can be transmitted.In MBSFN sub-frame 1205, the transmission of this type of control signal may need in order to the transmission (PHICH such as, confirmed for mixed automatic repeat request (HARQ), the PDCCH controlled for uplink scheduling license and/or up-link power) in support uplink direction.The length of uni-cast portion 1210 can semi-staticly be configured to specify that all communities related to during it transmits MBSFN are identical.But this can be contrary with the L1/L2 control section 1220 of non-MBSFN sub-frame, in the portion, length dynamic change (such as, changing by the basis of subframe), and send on PCFICH by signal.But, in MBSFN sub-frame 1205, also still PCFICH can be had.
MBSFN part 1215 can be provided for the remainder of MBSFN sub-frame 1205, and the mapping that wherein can transmit coding controls header (MCH).In MBSFN sub-frame 1205, different CP (such as, expanding CP) can be adopted.The uni-cast portion 1210 of MBSFN sub-frame 1205 can use the CP identical with non-MBSFN sub-frame.This CP can be different from the CP of the remainder for MBSFN sub-frame 1205.
In MBSFN sub-frame 1205, the transmission in first OFDM symbol (transmitting under antenna case in the second OFDM symbol with use four) of the first time slot of MBSFN sub-frame 1205 of the specific unicast reference symbols in community.In addition, in MBSFN sub-frame 1205, other MBSFN reference symbol can be transmitted in the MBSFN part 1215 of MBSFN sub-frame 1205.The all communities related to during the position of these reference symbols and reference signal sequence can transmit MBSFN are identical.These MBSFN reference symbols can allow the aggregated channel estimating all communities related to during MBSFN transmits.
Will be appreciated that in LTE framework, it can be differentiable that the MBSFN transmission on mixed carrier and the MBSFN on special carrier transmit.MBSFN on mixed carrier transmits hint MBSFN and transmits and common unicast service (that is, in different subframe) executed in parallel on same carrier wave.MBSFN on special carrier transmits hint MBSFN and is transmitted in be exclusively used on carrier wave that MBSFN transmits and performs (that is, this type of carrier wave not having other clean culture transmission).In this regard, can suppose that MBSFN special carrier is do not have corresponding uplink carrier, and therefore in the subframe for MBSFN special carrier without the need to any clean culture controlled area.
As mentioned above, the support of E-UTRAN standard is used for specific or four antenna ports of collective reference signal in community and an antenna port for DRS (Dedicated Reference Signal).In this regard, E-UTRAN standard has displayed the restriction suppressing to further expand.Such as, other reference signal may be needed distinguish the more multi-antenna port of support more current than E-UTRAN standard.Additional or alternative, may need new signal type to be introduced E-UTRAN standard to support application in the future.Desirable also by be introduce these forms enhancing signal and do not affect legacy devices.
